parentvfs: add find_inode_nowait() function (diff)
ext4: add optimization for the lazytime mount option
Add an optimization for the MS_LAZYTIME mount option so that we will opportunistically write out any inodes with the I_DIRTY_TIME flag set in a particular inode table block when we need to update some inode in that inode table block anyway. Also add some temporary code so that we can set the lazytime mount option without needing a modified /sbin/mount program which can set MS_LAZYTIME. We can eventually make this go away once util-linux has added support. Google-Bug-Id: 18297052 Signed-off-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
